Periprocedural imaging assessment for percutaneous Left Atrial Appendage (LAA) transcatheter occlusion can be obtained by utilizing different imaging modalities including fluoroscopy, magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound imaging. Given the complex and variable morphology of the left atrial appendage, it is crucial to obtain the most accurate LAA dimensions to prevent intra-procedural device changes, recapture maneuvers, and prolonged procedure time. We therefore sought to examine the accuracy of the most commonly utilized imaging modalities in LAA occlusion. Institutional Review Board (IRB) approval was waived as we only reviewed published data. By utilizing PUBMED which is an integrated online website to list the published literature based on its relevance, we retrieved thirty-two articles on the accuracy of most commonly used imaging modalities for pre-procedural assessment of the left atrial appendage morphology, namely, two-dimensional transesophageal echocardiography, three-dimensional transesophageal echocardiography, computed tomography, and three-dimensional printing. There is strong evidence that real-time three-dimensional transesophageal echocardiography is more accurate than two-dimensional transesophageal echocardiography. Three-dimensional computed tomography has recently emerged as an imaging modality and it showed exceptional accuracy when merged with three-dimensional printing technology. However, real time three-dimensional transesophageal echocardiography may be considered the preferred imaging modality as it can provide accurate measurements without requiring radiation exposure or contrast administration. We will present the most common imaging modality used for LAA assessment and will provide an algorithmic approach including preprocedural, periprocedural, intraprocedural, and postprocedural.

Abstract Background This study evaluated surface endothelialization of Watchman occluder (Boston Scientific) through comparing relevant indicators before and left atrial appendage closure (LAAC) in 68 non-valvular atrial fibrillation (AF) patients.Methods Patients were monitored preoperatively by transthoracic echocardiography (TTE), transesophageal two-dimensional and three-dimensional echocardiography (2D-TEE, 3D-TEE), intraoperatively by 3D-TEE and angiocardiography, and followed at 3 and 6 months after operation by TEE.Result It showed that the inner diameters of LAA ostium measured by TEE at 0°, 90° and 135° before operation were correlated with corresponding maximum diameters measured by angiocardiography. The depth of LAA ostium measured at 90° was correlated with the maximum depth measured by angiocardiography. The left atrial diameter, left ventricular diameter and left ventricular free wall E/E' decreased postoperatively. Compared T-test showed that BNP level and persistent AF might be risk factors for spontaneous echo contrast (SEC) or thrombosis of LAA. Multiple linear regression identified persistent AF, preoperative LAA spontaneous echo contrast or recent thrombotic event, and history of embolism in other parts were the influence factors of occluder endothelialization.Conclusion: BNP level and persistent AF may be risk factors of left atrial appendage thrombosis. Treatment of AF and thrombus in left atrial appendage or other parts are beneficial to the prognosis of LAAC patients.
